Abstract

Abstract: N2 fixation is a challenging and rewarding issue. However, the traditional Haber–Bosch process consumes a large amount of fossil fuels, resulting in serious environmental pollution. Instead, N2 electroreduction is a promising way to convert and utilize N2 . Among various N2 electroreduction methods, combining N2 reduction with batteries is simple and efficient. Here, a composite of ultrasmall Mo2 C particles highly dispersed on N‐doped carbon nanosheets is prepared, and it is applied as the air cathode for Li–N2 batteries. Li–N2 batteries show high discharge capacity and superior reversibility, demonstrating that the Li–N2 battery is a promising platform for N2 electroreduction and electrochemical energy storage.
